When cranking mini it spits and sputters and when i give it gas to riv the motor up nothing happen?

What is your question?

When you crank it with go dead a few times, when riving the engine up and when it goes under 2000rpm motor with die then as well. Once I am able to give it gas it will pops like backfire. Once the car stays cranked and warms up it doesn't do it anymore. Only when you crank it after setting for hours at a time is when the problem with cranking happens

What makes this problem better or worse?

once it gets going its fine
